Effect of Welding Heat Cycle Peak Temperature and Heat Input on HAZ Grain Size of SMA490BW Corrosion Resistance Steel

Abstract:

Welding thermal cycle of SMA490BW corrosion resistance steel with different heat inputs were simulated by using Gleeble-3500 thermo-mechanical simulator to investigate the grain size of the heat affected zone (HAZ). Results show that welding heat cycle peak temperature has great influence on the grain size with the same other conditions, the higher peak temperature is the bigger grain size is; in different welding thermal cycling conditions, line energy affects grain size differently; specimens which experienced two thermal cycle have smaller grain size than which experienced just one thermal cycle.
